I'm wondering about the effects of different durations and intensities of pain on the body. So the two can be compared, let's say that the cause of pain is the same in both cases, but in one the duration is shorter although the pain is more severe, and vice versa. Also, by effects, I mean biological but also psychological (which is probably more interesting), but the latter might be out of the scope of this site, so forgive me if it is.
For the sake of a (rather grim) example, if someone is exposed to a painful stimulus such as a mid-voltage shock for a long duration, and if someone else is exposed to a much higher voltage shock for a much shorter duration of time, which would produce worse effects on the body's normal functioning? (Somewhat morbidly, I should say to assume that they both live and do not die on the spot.) Since the answer very well might depend on the type of harmful stimulus, I'll give another example of a burn. If one is repeatedly subjected to a first-degree burn for a while and another is subjected to a third-degree burn only once, which is worse?
Upon pondering the question, it seems that the psychological effects would be more interesting since they should be roughly the same regardless of the type of stimulus, but biologically the effects obviously differ.
Thank you for your time, and any responses or thoughts on this would be greatly appreciated.
Edit: Obviously most experiments to test this would be subjective and unethical, especially in the case of psychological effects, so just an opinion from someone more knowledgeable in biology is more than fine.
